Beit known that I, MICHAEL D. SCHALLER, a citizen of the United States,residing at Lowell, in the county of Oneida and State of New York, haveinvented a new and useful Snow- Ilow, of which the following is aspecificaion.

The invention relates to improvements in snow plows.

The object of the present invention is to p rovide a simple andcomparatively inexpensive snow plow which will be adapted for operatingon roads in winter to level the same and to preserve them in propercondition for vehicle travel.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure l is a perspective View of a snow plowconstructed in accordance with this invention. Fig. 2 is a transversesectional view.

Like numerals of reference indicate corresponding parts in both thefigures of the drawings.

1 designates a sled provided at each side with bearings 2, and havingjournaled therein rock shafts 3 which are provided with oppositelydisposed arms i and 5 the former of which depend in recesses 6 at theside of the sled and have attached to them the ends of a supporting bar7 and the upwardly extending arms 5 are pivoted to the ends of aconnecting rod 8. An L-shaped standard 9 depends from the supporting bar7 and carries a scraper l0 which has pivotally secured to it anadjustable mold board 11 and which is adapted to be raised above theground by means of an operating lever l2 when itis not in use, and whichis adapted to be dropped below the adjacent runner 18 to bring it inoperative position. The mold board is adapted to throw the snow andearth excavated by the scraper outward and is adjustable by a horizontalbrace 14 so as to throw the earth a desired distance outward. Thescraper is provided with vertical sides 15 and 16 and serves as a scoop,and the front of the mold board conforms to the configuration of therear end of the scraper. The brace 14E is composed of two sectionsconnected by a bolt 17 and provided with perforations and adapted to bemoved on each other to increase or diminish the length of the brace 14,and thereby adj ust the mold board. The operating lever 12 is fulcrumedon the sled and is connected by a link-bar 1S with the connecting bar,and it is provided with latch mechanism arranged to engage a ratchet 19whereby the operating lever may be secured at the desired position tohold the scraper at the proper depth. By moving the operating lever thescraper is raised 0r lowered and may be thereby controlled.

A scraper is arranged at each side of the sled and they may be adjustedindependently to suit the condition of the road. The plow mechanism maybe applied to a long sled or to a pair of bobs if desired.

What I claim is- 1. In a snow plow, the combination of a frame, the rockshafts arranged transversely of the frame and located at the front andrear of the same and terminating at the sides of the frame in dependingarms having outwardly bent ends extending horizontally from the frame,the longitudinally disposed supporting bars carried by the outwardlyturned ends, scrapers suspended from the supporting bars, and means forturning the rock shafts to raise and lower the Scrapers, substantiallyas described.

2. In a snow plow, the combination of a frame, rock shafts journaled onthe frame, a supporting bar connecting the rock shafts, a scrapersecured to andcarried by the supporting bar, and a mold board pivotallyconnected to the scraper and adjustably connected with the supportingbar, substantially as described.

3. In a snow plow, the combination of a frame, rock shafts journaled onthe frame and having depending arms, a supporting bar connecting thearms, a scraper secured t0 the supporting bar, a mold board pivoted tothe scraper, and a horizontal brace connecting the mold board with thesupporting bar and composed of two sections adjustably secured together,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

MICHAEL D. SCHALLER.
